BM64070MUV Description
BM64070MUV is the pre-driver IC of sine wave drive for three-phase brushless motor driver that supports 48 V power supply controlling the motor driver constructed in external FETs. The sensor-less drive that the hall devices for the position sensing are unnecessary is adopted. It has a speed feedback control function, and controls output PWM Duty by adjusting the rotational frequency characteristics for the input...
